   cnBeta reports that Andrej Karpathy released HackerTube, a weekend project that uses recommendations found in two decades of Hacker News comments to assemble a video library. Karpathy says Claude Code, running Claude Opus 5.5 with medium reasoning effort, analyzed 43 million comments, selected 6,454 repeatedly recommended videos, and assisted with development and deployment. He also says the project took about two hours, while HackerTube requires no account and stores usage state in the local browser session.

   Pizza Bot: an AWS team open-sources a background agent inbox

   InfoQ reported that a team of Amazon Web Services developers has open-sourced Pizza Bot, a self-hosted application that runs AI agent tasks in the background — on schedules or via Webhooks — and returns results through an email-like inbox. Agents can delegate work to specialized workers and pause for human approval, with the inbox organizing items into All, Unread and Pending queues and an activity panel showing task progress. The Apache 2.0, client/server tool keeps agent state, threads, checkpoints, attachments and logs in a user-controlled local folder and stores credentials in the OS keystore; its authors say it supports multiple model providers, MCP servers and agent skills. The report stresses it is a community project, not an official AWS service with support or an SLA, and some Hacker News commenters questioned whether it can replicate the skills and integrations that made the internal version work.

   Open-source last30days agent skill trends on GitHub for cross-platform research

   The GitHub Trending Python list features mvanhorn/last30days-skill, an open-source "agent skill" that searches Reddit, X, YouTube, Hacker News, Polymarket and the web in parallel and has an AI agent synthesize a cited brief. The project README says it is MIT-licensed with no tracking, ships 2,700+ tests, and installs via the Claude Code plugin marketplace, npx skills, or Grok Build; Reddit, HN, Polymarket and GitHub are said to work with zero configuration. The README also says it tracks the current v3 pipeline and ranks results by engagement signals such as upvotes, likes and prediction-market money, all of which are the project's own claims.
